A couple ports to check out. The first stays close to the original games where D2X-XL is more like the EDuke32 of Descent/II.
If it's still doing it and you need a binary that I know works then I'll just share mine.
D2X-XL is a lot more comparable to Darkplaces for Quake than EDuke32 (or GZDoom for that matter).
The reason is that, similar to Darkplaces, the base port already adds a lot of very fancy visual effects, such as smoke particles, explosion effects, light coronas, real time shadows, and even a different HUD, which stray quite far from the original's pixelated look.
D2X-XL goes a lot further than Darkplaces with Quake however, even adding numerous changes to gameplay, such as a radar, the ability to zoom in with the Vulcan or Gauss cannon, dual missile launch and even bullet time (for some reason). You can toggle them, but they are there nonetheless.
EDuke32 or GZDoom on the other hand mostly leave these kinds of changes up to the modders to implement, even with the Polymer/OpenGL renderer active.
Additionally, a couple of years ago I experienced a particularly nasty bug in D2X-XL related to savegames in secret levels (which normally aren't allowed) that somehow always made me respawn in the secret level when I died, no matter if I started a new game or not.
DXX-Rebirth is a lot less prone to bugs like this, as it keeps its feature list much smaller. That, the above, and the fact that D2X-XL doesn't seem to be in active development anymore is why I would recommend DXX-rebirth over D2X-XL, even for people who are used to ports like GZDoom.
